Granted, chances are good that young Mr. Bieber has never heard of Peter Noone, who performs here Sunday at Sycuan Casino. (Bieber, who turned 19 Friday, is still too young to get into Sycuan, but that’s another story.)

Regardless, it would be instructive for Bieber to study up on Noone, if not the latest edition of his band, Herman’s Hermits.

In his pre-Internet, pre-social-media heyday in the mid-1960s, Noone was an international teen-pop idol. He inspired deafening fan hysteria, not unlike Bieber now, as part of The Beatles-led British Invasion that also made stars here of fresh-faced young English groups from 'a' (The Animals) to 'z' (The Zombies).

As the lead singer in Herman’s Hermits, Noone scored a dizzying 18 U.S. Top 40 hits between late 1964 and early 1968. They include "There's a Kind of a Hush," “No Milk Today” and the mildly psychedelic “Museum” (which was written by hippie troubadour Donovan, featured a studio band that included future Led Zeppelin co-founders Jimmy Page and John Paul Jones, and used the same instrumental backing track for both the Donovan and Hermits' versions).

The there was the Hermits' 1966 hit "Dandy," which was written by Ray Davies of The Kinks, and the 1968 movie, "Mrs. Brown You've Got a Lovely Daughter," which co-starred Noone and Sheila White (who also was featured in the 1966 film "The Ghost Goes Gear," which teamed her with Steve Winwood and the Spencer Davis Group).

A former soap opera actor, Noone was only 15 when he joined the Hermits in 1963, two years after his parents nixed an offer for him to co-star in a film with Judy Garland. With his perky voice and teen-idol looks, Noone drew frenzied screams just as often as Bieber does today.

Moreover, some of his hits with the Hermits were as fluffy and innocuous as some of Beiber's, although -- in that pre-AutoTune era -- Noone sang all his vocals live at the Hermits' concerts. That fluff factor, incidentally, was largely fueled by the band's producer, Mickie Most, who believed the Hermits could appeal to parents as much as kids. The Who's first tour of the U.S. was as the opening act for Herman's Hermits.

Noone left the band in 1971. But during its brief commercial peak, he and the Hermits achieved worldwide record sales of more than 40 million in less than 40 months. But the number Bieber should really focus on is 45.

That’s how many years it’s been since the Hermits’ most recent U.S. hit, although Noone scored one solo hit in his native England with 1971’s “Oh, You Pretty Things!” (which was written by David Bowie, who also played piano on Noone’s version).

Despite this decades-long commercial drought, Noone still loves his job, as evidenced by the 36 U.S. concert dates he has scheduled between now and October, and the fact that he is on the road, year after year. And, in contrast with, say, The Turtles -- with whom he shared a concert bill at Humphrey's back in the last decade -- Noone hit all his notes and was never out of breath for making the effort.
